Well, I also did a little bit poking around my display settings as you suggested a few posts ago to alehead. Here’s what I found:
- If I have Spotify on one of my Display panels when I start the first song, the Equalizer button shows up as expected. I can move Spotify to another display, and it keeps working.
- If I have Spotify on a different Display panel when I start the first song, the Equalizer button doesn’t show up. This remains the case even if I move Spotify to another display after starting the song. This is the case in my Debug snippet above.
- The display that doesn’t work has Scaling active, set at 125%. If I reset scaling to 100%, the Equalizer button shows up as expected (though clearly this isn’t really an acceptable workaround).
- I tried changing the DPI setting in equalify2.eq - was “-1”, I tried both “192” and “120” and the Equalizer button didn’t show up on that display.
- If I change the Windows Compatibility settings on the Spotify shortcut to use Application Scaling (under Compatibility -> Change high DPI settings -> Override high DPI scaling behaviour. Scaling performed by -> Application) the Equalizer button shows up. (I can live with this in the short term, but it would be nice if I didn’t have to use this as a workaround.)
For comparison, here’s the Debug log from when Application Scaling is used:
